A study  that appeared in the Journal of Nervous and Mental Disease (June, 2007) looked at the effect acupuncture had on patients suffering from Posttraumatic stress disorder (PTSD). The subjects of the study were 73 people diagnosed with PTSD. The researchers evaluated the patients for depression, anxiety and impairment. The patients were divided into three groups, one group was a control group that was placed on a waiting list to receive therapy. The other two groups received either acupuncture or cognitive-behavioral therapy in a group setting for a period of 12 weeks. The group receiving the acupuncture enjoyed improvements similar to the group receiving the cognitive-behavioral therapy. Both of the treatment groups fared better than the control group. This was a small, pilot study and the results are preliminary. More research needs to be done in this area.
